Perhaps you should try some spelling variations:
communication contexts » communication concepts, communication content, communicative context
comments dimension » community dimension, elements dimensions, comments discussion
contexts comments » context comments, concepts comments, contexts community
tuple spaces » tuple space, type spaces, triple space
scale spaces » scale space, sample spaces
use spaces » phase spaces, gauge spaces, whose spaces

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication contexts comments dimension ((tuple spaces) or (((scale spaces) or (use spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication contexts comments dimension ((tuple spaces) OR (((scale spaces) OR (use spaces)))).
• Adding a wildcard symbol may retrieve word variants: communication contexts comments dimension ((tuple spaces) or (((scale spaces) or (use spaces))))*.
